2017 Map of Petersburg A-1 SE

About this map

Deer Island dominates the eastern half of this coastal survey, situated within the expansive wilderness of the Tongass National Forest. The map documents the intricate coastline of Southeast Alaska, where the Seward Passage and Ernest Sound meet the open waters of the Gulf of Alaska. Navigational landmarks are scattered throughout these waters, from the isolated Blanche Rock to the clustered Niblack Islands. On the mainland and larger islands, the terrain is defined by prominent coastal features such as Kuakan Point and Thoms Point, alongside sheltered inlets like Southwest Cove. The layout of the islands, including Bold Island and Found Island, illustrates the complex maritime geography of the Alexander Archipelago. This 2017 edition provides a contemporary topographical perspective on the natural harborages and shoreline configurations used by modern mariners and researchers.
